Within three decades people will no longer be having sex to procreate, a professor from Stanford University has said. Hank Greely, the director of Stanford’s Law School’s Center for Law and the Biosciences, believes the reproductive process will begin with parents choosing from a range of embryos created in a lab with their DNA. Although this can already take place, Mr Greely believes it will become far cheaper to do so and couples will opt for this method. The process involves taking a female skin sample to create stem cells, which is then used to create eggs. These eggs are then fertilised with sperm cells, resulting in a selection of embryos.
